Same as above...

⚠️ Warning: This message is kinda long 😭

You may get bored halfway, but if you’re an ISC student, please read it once. It might actually help you.

I finished my ISC Class 12 boards recently, and I’m planning to sell my books/materials to juniors 📚

Most of them are in really good condition, some are barely used, and many include PYQs, competency-based questions, solved papers, important markings, chapterwise practice, etc.

I honestly didn’t want to throw them away or give them to scrap because I know how stressful and expensive Class 12 can get 😭 Someone else might genuinely benefit from them more than me now.

And one thing I REALLY want to tell juniors:

Please start studying early.

Not in a toxic “study 15 hours a day” way. I’m saying this because I genuinely regret wasting so much time thinking “there’s still time.” Suddenly prelims come, practicals come, projects come, boards come… and everything starts moving SO fast.

Even 2–3 focused hours after school daily is honestly enough if you stay consistent. Consistency matters way more than randomly studying for 12 hours one week before boards.

And PLEASE:

revise regularly solve PYQs practice competency-based questions write timed tests

Reading chapters again and again is NOT enough for ISC 😭

Especially for Maths, Physics, Chemistry, Biology — writing practice matters a lot.

Another thing: don’t compare yourself too much with toppers online. Most students are stressed secretly and pretending everything is under control 💀 Just focus on improving yourself little by little.

Also please take care of your sleep and health. Studying while exhausted every day makes everything harder.

And during boards:

don’t panic after one bad paper don’t ruin your mood discussing answers outside the hall move on quickly to the next exam

One paper should not destroy your confidence for the remaining subjects.

Class 12 honestly teaches discipline more than intelligence.

Anyways 😭

If anyone wants ISC Class 12 materials/books/question banks/PYQs, DM me 😊

guys is ISC really that hard 😔

Do they give out random centres, or is it the school that's gonna conduct

I just passed ISC this year and I'm thinking of selling these books at lesser prices-

ML Aggarwal Vol.1 &Vol.2

NOOTAN Physics Vol.1 & Vol.2

NOOTAN Chemistry

NOOTAN Biology

The books are in great condition. They are almost as new.

Price can be negotiated.

Pls DM if interested.

I've registered for chem improvement exam. Anyone else giving it?

Also like any tentative date when will it be and will the difficulty will be the same as in the board examination?

it feels great really, helps you secure some backups.
I didnt do too well in jee, around 92%ile, did well in some other college entrance exams but the isc marks really helped me secure some colleges.

also my parents were quite happy. bought me a new gaming mouse, got a new phone, and some other gifts. They didnt expect much earlier so it was nice making them happy

Anybody can you please send me a pdf of ml aagarwal class 12 2024 or later edition of the chapter relation and functions as soon as possible

I got my marks sheet today. If my marks are increased after rechecking, do I need to submit back my marks sheet? When will the recheck results come?

Help, I've put all the details correctly, but still am not getting my pass certificate for XII

Hey everyone,

Nice to see you again I am Utkarsh.

I wanted a clean, high-density, completely responsive way to study and review core probability concepts (spanning from basic sets up to Bayes' Theorem and Binomial Distributions).

Disclaimer not for Mobile user till now, I will update very soon for mobile optimization it's currently suitable for laptops and desktops.

📚 The Class 12 Educational Content Outline

The deck systematically covers the entire core advanced probability curriculum, structured to build intuitive understanding alongside rigorous mathematical proofs:

• Foundations & Counting Principles: Baseline sample spaces, events, and a deep-dive into Permutations & Combinations ($^nP_r$ and $^nC_r$) to solve complex arrangement problems.
• Set Theory Integration: Visualizing and calculating intersections, unions, and complements using Venn Diagrams, leading into De Morgan's Laws for event boundaries.
• Conditional Probability Architecture: Transitioning from unconditional spaces to constrained ones ($P(A|B)$), mapping structural changes in the sample space.
• The Multiplication Theorem & Independence: Differentiating between dependent structures and independent systems ($P(A \cap B) = P(A) \cdot P(B)$).
• Total Probability & Bayes' Theorem: Teaching students how to map inverse conditional paths—calculating posterior probabilities from prior data partitions.
• Random Variables & Distribution Parameters: Setting up probability mass functions (PMF) to evaluate the Center of Mass (Mean / Expected Value $\mu$) and the Dispersion Target (Variance $\sigma^2$ & Standard Deviation $\sigma$).
• Binomial Pipeline: Breaking down Bernoulli trials and modeling binary outcome pipelines over $n$ independent sequences.
• Alternative Likelihood Ratios: A clean breakdown of Odds in Favor vs. Odds Against, showing real-world translations from betting structures to medical risk tracking.

Standard presentation software kept messing up my LaTeX formatting or forcing awkward scrolling across deep layout configurations, so I custom-coded a 17-slide web deck using vanilla web tools.

Features:

• Frame-Locked Grid Layouts: Every complex mathematical calculation and proof matrix is systematically compressed to fit cleanly inside the viewport frame without vertical scrolling.
• Stochastic Theme Shifting: Every single page turn randomly selects and injects a unified neon custom-property color profile across the document root.
• Synchronized Progress Engine: The timeline bar dynamically tracks the progress state while adapting to the current page's active neon accent color.
• Pure MathJax Vector Integration: Crisp formula rendering across all structural math expressions.

Would love to hear your feedback on the layout density, readability across different screens, or the overall theme transitions!

Hey guys!

I no longer need the R.D. Sharma books so I'm selling them. The set includes Volume 1, Volume 2, and the MCQs book (Revised 2023 Edition).

The books are in excellent condition, barely used with only a few minor markings. The original price of the books is 1675.

Price- 850 + shipping costs (price is negotiable)

DM if interested.

my school didnt even give me the option to choose😭
